2. The parameters of 2.G502 are good. I especially like the G502 with five counterweight blocks. You can adjust the weight of the mouse yourself.
3. Just choose a mouse that suits you. A good mouse is more stable and economical. You can see Lei Bai's V2 Logitech G 100s, Razer's purgatory viper and so on. You can look at Logitech G402 and G502, Lei Bai V9 10 and so on. They are all very good mice.
4, mine is 402, which is quite easy to use. You have to go to Logitech official website to open a 402 cheap mouse and lose frames. As soon as you turn fast, you will automatically look at the sky and the ground.
